default behavior.</p>
<h2 id="sec_attention">注意</h2>
<p>On Windows Systems, error dialog boxes from the operating system can occur
when dependency modules of the interface are not found, e.g., the according
SDK was not installed. The occurrence of the error boxes can be controlled by
setting Windows' Error Mode. Please refer to the description of SetErrorMode
within the Windows MSDN documentation.
